Filed: 1989-09-22
Abstract: PURPOSE:To improve adhesion strength of a thin film formed on polyimide resin by forming a polyimide resin film between an insulating layer of polyimide resin and a wiring layer thereon with the top side of a conductor pillar exposed. CONSTITUTION:A polyimide resin layer 2 is formed on a principal face of a ceramic board 1; a thin film layer 3 is formed; a photoresist 4 is applied; and pattern exposure is carried out. Then, development treatment is performed to form a plating layer 5. Photoresist 7 is further applied to the photoresist 4. A conductor pillar 6 is formed by electrolytic plating of Cu through exposure and development processes. After the photoresists 4, 7 are removed, the thin film layer 3 of an unnecessary part is removed by etching treatment and a wiring pattern 8 is formed which consists of the thin film layer 3 and the plating layer 5. A polyimide resin layer 9 is formed covering the conductor pillar 6 and the wiring pattern 8. A surface of the polyimide resin layer 9 is polished to expose the top side of the conductor pillar 6. A polyimide resin film 10a is formed on the polished polyimide resin layer 9.

Title: Treatment of organic waste water
Inventor: IKEHATA TAKAO
IPC: C02F3/14
Filed: 1984-11-22
Abstract: PURPOSE:To remove effectively nitrogen and phosphorus by eliminating the deficiency of an org. carbon source during denitrification reaction in a water way for treating sewage thereby preventing the outflow of the sludge having the large BOD quantity in the anaerobic stage from said water way into a settling basin and preventing the anaerobic biological reaction in the settling basin. CONSTITUTION:Aeration into the water way 11 for treating sewage is intermittently executed and part of feed water is introduced into the water way 11 when the aeration to the water way 11 is stopped. The sludge from the water way 11 is post-aerated by a post-aeration tank 19 in the mid-way of introducing said sludge into the settling basin 13. The settled sludge from the settling basin is constantly and continuously returned by a pump 23 to an absolute anaerobic tank 14. The sludge is returned to the water way 11 by a pump 23 when the sludge level in the settling basin exceeds a prescribed value. The return of the sludge to the water way 11 is stopped and the sludge is discharged into an excess tank when the sludge level rises. The effective removal of nitrogen and phosphorus from the org. waste water is thus made possible.

Title: Sealed battery
Inventor: TSUJI HARUHIKO
IPC: H01M10/05
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To break current surely, and discharge inside gas outward so as to prevent the explosion of an armor can when the internal pressure of a battery rises by providing a protrusion portion having predetermined braking strength on the safety valve side of a sealing plate, and welding and connecting the protrusion portion to the safety valve. SOLUTION: When gas is generated resulting from the disorder of a power generating element 3 so that the internal pressure rises rapidly, the gas passed through the gas purging hole 7a of the sealing plate 7 acts on the inside of the safety valve 9 so as to break the protrusion portion 7b of the sealing plate 7 to break an electric circuit. Further, the safety valve 9 is deformed so as to cleave the safety valve 9. Thereby, the gas is discharged outside via the gas purging hole 8a of a battery lid so that the explosion of a battery is surely prevented. When temperature rises resulting from the disorder of an power generating element 3, the electric resistance of a PTC 14 interposed between the battery lid 8 and the safety valve 9 is increased so as to break current flowing to the battery lid 8.

Filed: 1987-10-02
Abstract: PURPOSE:To drive a semiconductor laser element at high frequency by providing a dielectric plate between a carrier and an electron cooling element or/and between the electron cooling element and a container. CONSTITUTION:The dielectric plate 13 is provided between the carrier 2 and electron cooling element 3 or/and between the electron cooling element 3 and container 4.

Title: Semiconductor device
Inventor: FUKUSHIMA YASUO
IPC: H01L23/28
Filed: 1988-10-03
Abstract: PURPOSE:To prevent the crack development because of thermal stress in a resin molding layer by causing the rear of an island part of a lead frame on which a semiconductor element is mounted to act as a part of outside walls. CONSTITUTION:An island part 9 of a lead frame on which a semiconductor element 5 is mounted is formed into a recessed shape having sidewalls 10 around the island part and the rear of the recessed part which protrudes below the island part 9 is sealed with a resin molding layer 8 so that the above rear makes up a part of outside walls of a semiconductor device. As the resin molding layer 8 does not exist at a lower peripheral part of the island part 9, stress concentration on the lower peripheral part of the island part 9 is suppressed even though thermal stress is applied to the semiconductor device; besides, the resin molding layer 8 does not exist in the above part 9. The development of cracks is thus prevented.
